In order to improve the satisfaction of users and achieve the appreciation of resource service,it is important to select an optimal resource service,which also satisfies the demand of users,from all candidate resource services which have the characteristic of identical or similar functions.This paper represented all users' evaluations on non-functional QoS assumed that by triangle fuzzy numbers,via integrating the fuzzy set theory and the TOPSIS method,and it proposed a fuzzy TOPSIS-based resource service optimal-selection algorithm.In this algorithm,it took into account not only the user's feeling and transaction experiences,but also many other factors existing in the non-functional QoS evaluation aggregation of resource services(such as time,user reputation,evaluation consistency,etc.).Experimental results reveal that this algorithm has high accuracy,and can prevent the impact from the malicious evaluations at some extent.
